Well, you did: :)

>>> +        vmport_rpc = isa_try_create(isa_bus, "vmport_rpc");
>>> +        if (vmport_rpc) {
>>> +            qdev_init_nofail(DEVICE(vmport_rpc));
>>> +        }

vmport does have a port.  vmport_rpc doesn't, it would use the same port
as the main vmport device (which would dispatch to vmport_rpc).
